3-Phase Earthing Device

Ref. SS 428 91 01, EN 61230, EN 61235
Earthing device JSGT or JSGH are for use on overhead transmission lines,low and high voltage 0.4 – 52 kV.
Line clamp’s clamping range: JFKS 20: 3-20 mm, JFKS 30: 5-30 mm. The device has a rubber insulated bayonet type connector fitting for con-
necting an alternative earthing device such as JSGO or JSGL and earthing device JK31-DXF, JSGR, JSGJ, JK238-DXF.
The line clamps conducting parts are made of hardened AlSi-alloy.
Steel components are made of stainless steel. The insulating pole is made
of fiberglass reinforced vinyl ester and is sealed. The earthing cable, made of highly flexible ESTPR-insulated copper strands, has sealed cable
connections, which prevent humidity from penetrating the cable. The earthing cable is conected by compression to the line clamp (also available with cable lug connection).
As standard the earthing device is marked for 24 kV.
Case: DFO/JSKL3.
